known as “Sullivan’s Early Prolific,’ and it is grand wheat. Mr. Kennedy 
has cultivated his land properly, or else it is hardly likely that he would have 
had such a grand crop, even from this undoubtedly prolific variety. There’s no 
doubt that farmers will be anxious to get some of the grain from Mr. Kennedy 
for seed; and as the wheat is being thrashed with a roller, it ought to be in 
good condition. We forgot to say that the sample we received from Mr. 
Kennedy was not picked, but represents a fair sample from the whole bulk— 
and there wasn’t a faulty grain in it.—Sydney Stock Journal. 
COLD STORAGE FOR EGGS. 
TirerE can be no doubt that eggs may be perfectly preserved by depositing ~ 
them in a cool chamber for a considerable length of time. The latest proof of 
this comes from the Sydney Stock Journal, which states that an egg was opened 
at the Board for Exports’ office last month. The egg was fourteen months 
old, as it was put in the cooling chamber at Pyrmont on 10th October, 1897, 
and it was as good as the day it was put in. We cooked a couple of eggs 
that had been in the cooling chambers for over three months, and they were 
for all the world like new-laid eggs—the milky appearance and all. 
TO COMPARE THE READINGS OF DIFFERENT 
THERMOMETERS. 
Tue Centigrade Thermometer is so often used instead of Jahrenheit’s 
instrument in scientific work in the sugar-mill, in the dairy, &c., that it is 
convenient to know how to represent the degrees of one in terms of another. 
We lately noticed in a dairy the comparative degrees of Centigrade and 
Fahrenheit written on the wall of the coolroom for the guidance of the 
operators. 
Now, here are a few simple formule embracing the three thermometers 
in general use which are based on the fact that 9 degreey Fah. = 5 Centigrade 
= 4 Réaumur. 
TO REDUCE CENTIGRADE TO FAHRENHEIT. 
Centigrade degrees xX 9 
" + 82 = Fahrenheit degrees. 
9) 
EXAMPLE. 
The freezing point of the Centigrade thermometer being 0, what is the 
corresponding degree of Fahrenheit’s thermometer? By the above formula— 
0x9 
5 + 82 = 0 + 82 or 82 degrees, the freezing point of Fahrenheit. 
What degree of Fahrenheit will correspond to 100 degrees Centigrade ? 
100 x 9 
—5 + 82 = 20 x 9 + 82 = 180 + 82 = 212 degrees. 
Thus, 100 degrees C. and 212 degrees F. indicate the respective boiling 
points. 
TO REDUCE FAHRENHEIT TO CENTIGRADE. 
Fahrenheit de — 32 x 5 F ; 
SS = Centigrade degrees. . 
EXAMPLE. 
The freezing point of Fahrenheit being 32 degrees, what is the corres- 
ponding degree of the Centigrade thermometer ? 
32 — 32 5 : : ; 
aot? = 0, the freezing point of Centigrade.
